“…Salt accumulation in leaves often induces chlorophyll decomposition [11]. Hence, chlorophyll content is used as one of the salt tolerance characteristic of plant [8]. Non-significant difference of chlorophyll content during salt stress indicated the ability of plant to adapt with salt stress because delay of chlorophyll degradation during salt stress is one of the characteristics of salt tolerant species [3].…”

“…The inhibition of growth of Jatropha when exposed to high salt (NaCl) concentration could be attributed to three specific growth constraints, which are: (i) drastic changes in the plant water status caused by osmotic effect of salinity, (ii) increase of the ion toxicity concentration, and (iii) the nutritional imbalance caused by alteration in the absorption of essential nutrients [15]. Dry biomass reduction pattern could be caused by reduction of CO 2 availability caused by stomatal closure which can induce a further biomass reduction through photosynthesis suppression [8]. The growth measurement result indicated that both Jatropha interspecific hybrid and non-hybrid represented by some of its varieties could be suspected to have a moderate salt tolerance ability.…”

Interspecific hybrid of Jatropha curcas x J. integerrima is expected to answer the low oil yield problem of Jatropha (Jatropha curcas L.). However, as a novel invention, research concerning on Jatropha interspecific hybrid is still limited especially in the aspect of its adaptability to unfavorable environment such as salt stress condition. It is interesting to know how Jatropha interspecific hybrid responses to salt stress condition due to the moderate salt tolerance ability of its mother plant (J. curcas L.). The objectives of this study were to compare the growth and physiological response of interspecific hybrid and non-hybrid Jatropha under salt stress. Three varieties of both interspecific hybrid and non-hybrid Jatropha seedling were exposed with 3 levels of sodium chloride treatment in Hoagland media solution which are 2.0 (control), 8.0, and 16.0 dS m-1 for 7 weeks. The parameters measured include plant height, number of leaves, shoot dry weight, specific leaf area, chlorophyll content (SPAD Index), leaf water potential, and leaf solute concentration. V2 (interspecific hybrid) showed the highest potential as moderate salt tolerant variety among experimental Jatropha varieties due to its increasing trend of leaf number, dry weight, and total leaf area at moderate salinity level (8 dS m-1). KUBP 35 and KUBP 40 showed the best growth performance under salt stress among experimental Jatropha varieties, but its potential to be moderate salt tolerant variety was still lower than V2 variety. The solute concentration, osmotic potential, and turgor potential of both interspecific hybrid (V2) and non-hybrid variety (KUBP 35 and KUBP 40) showed an increasing pattern which could be implied as an adaptive response to salt stress. This study has showed that Jatropha interspecific hybrid might have an adaptive physiological response to salt stress and could be considered as potential moderate salt tolerant variety under salt stress.

“…It has been assumed that salt stress enhanced the production and reduction of protein which causes osmotic adjustment [30]. The response of different plants to salt stress depends on the degree of their tolerance and on type, level and duration of osmotic substrate as reported by Hishida et al [31] and Hossain et al [32]. Increasing salt concentration decreased protein content such reduction might be due to protein hydrolysis Klyshev and Rakove [33], disturbance in cation balance Soakvan and petrouan [34], increase in hydrolyzing enzyme such as protease Garg and Garg [35] and Ebad et al [36].…”

Background: Moringa tree is a drought resistance tree, fast-growing, Moringa leaves, flowers and pods are a food source for human and animals. It is a rich source of calcium, iron and a good source of vitamins, B, A, C, amino acids. Shortage of water resources for irrigation especially in reclaimed soil considered is one of the great problems to cultivate traditional crops. Thus, nowadays the use of the non-traditional source of water, such as saline water is very important. Results: The obtained data recorded that the lowest level of salinity (4000 ppm) decreased plant height, fresh and dry weight of leaves, the stem fresh and dry weight, stem diameter recorded decreased. Increasing salinity levels up to 16000 ppm high reduction was registered in the previously mentioned parameters except for leaves number. The interaction between salinity and proline concentration exhibited in most cases reduction in total chlorophyll. Carbohydrate content, protein, nitrogen%, calcium%, recorded reduction in most cases under saline condition and their interaction with proline. While, Sodium %, Cl- percentage and proline content recorded increments in most cases under the previously mentioned circumstances. Conclusion: The results were nearly ascending order with increasing of salinity level. Increasing salinity to 16000 ppm decreased significantly the values of vegetative growth and almost all cases of chemicals constituents were reduced.

“…Plant height was found to decrease gradually with the increase of salinity levels. Salinity was attributed to the reduction in water content and water potential of plant tissues, which resulted in internal water deficit to plants (Hishida et al, 2013). Accumulation of Na + , Cland retardation in the uptake of macronutrients especially Na + and Ca 2+ cause reduction in plant growth (Juan et al, 2005;Dasgan et al, 2002).…”

A pot experiment was conducted in the net house of Department of Genetics and Plant Breeding, Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh, during the period of November, 2017 to March, 2018 to observe the performance of four tomatillo genotypes under three salinity (NaCl) treatments based on their agro-morphogenic traits. A two factorial experiment was conducted which included four tomatillo genotypes (Factor A) viz. G1 (SAU tomatillo 1), G2 (SAU tomatillo 2), G3 (PI003), G4 (PI004) and two salinity (NaCl) treatments with a control (Factor B) viz. T1 (Control), T2 (8 dS/m), T3 (12 dS/m) and was outlined in Completely Randomized Design (CRD) with three replications. The observed results showed that, both of four tomatillo genotypes (G) and three salinity treatments (T) had their independent significant influence and also had significant influence in their G×T interaction between different agro-morphogenic traits. Almost all traits responded negatively (%reduction) under the increased level of salinity treatments. Considering the minimum %reduction in yield and its contributing traits under both slightly (T2: 8 dS/m) and moderately (T3: 12 dS/m) salinity condition, genotype G1 and G3 could be recommended for cultivation and further trial in the salinity affected southern region of Bangladesh. The maximum reduction in days to maturity was found in genotype G1 and G4 and could be served as parent materials for further hybridization or genetic transformation program.
